Carbon and Manganese Transformations at the Continent-Ocean Margin Quantified with the ZAPS Instrument Package

摘要

We use innovative experimental approaches to measure the extent of biogeochemical interaction driven by the input of terrestrial organic carbon to the coastal oceans. The evolution of organic carbon from continents to oceans is not well understood. Remineralization of this carbon plays an unknown but apparently important role in stimulating productivity. This process and associated phenomena also affect ocean color, turbidity, and elemental recycling. Our long range goal is to quantify these processes in space and time. Quantification of biogeochemical change at the land-ocean boundary requires that we gain better insights into fundamental relationships between dissolved organic carbon and other parameters, such as total suspended particulate matter and dissolved metals.
